Abstract
A structural arrangement for an embedded and sealed railroad track and a method for its installation to provide a gutter defined along the rails of such a railroad track extending along or across a street or highway with rail tops at pavement level. Rubber filler bodies are held in place along the sides of each rail by retainer strips which lock into place on the filler bodies. A retainer form holds the filler bodies in place and provides space for the retainer strips when pavement materials are cast in place along the rails. Protective caps and sealing structures are installed before pavement materials are cast in place, to exclude the paving materials from space needed as a gutter along the rails to provide access to the rails and to spaced-apart supporting structures to which the rails are fastened, and to keep foreign materials from getting on the top of the rails and prevent them from becoming caught between the rails and the adjacent filler bodies.
